    2000 GP1200R no spark please help

    Yesterday i thought I would start my GPR for the first time in a few years, I found I had no spark. I initially tested the water temp sensor, it passed I think 8k ohms or so but it looked correct for the temperature.
    CDI was putting out very little to no volts. Lighting coil and pickup coil were both putting out low volts, rectifier was under spec.
    I thought it was the 5 wire plug coming from the stator because the it had ALOT of green corrosion inside and the previous owner told me if it ever doesn't crank to wiggle that connector. I cut it out and tried bullet connectors to rule out the plug, same results.

    Does this sound like a bad stator? A bad ground? All other connectors were relatively clean

    Also the PV servomotor doesn't cycle, that is controlled by the CDI correct? But the CDI needs power from the lighting coil and pickup coil to function.

    Oh yeah, battery is brand new voltage was 12.8, it cranked but no spark just to be clear

    Battery: 12.8 Volts

    Pickup Coil: Open Loop (445-545 ohms) 0 Volts (2.8-5v)

    Lighting Coil: .79 ohms (.49-.59) slowly climbed to 4.2 volts after 10 seconds of cranking (9v)

    Rectifier 6.8 volts (7v)

    CDI Output 0 volts (180-200v) on all 3 leads

    Water temp sensor 7.24 k ohms @95*F (37k-0.104k)

    Ign coil 1 .35 ohms (.26-.36)
    Ign coil 2 .36 ohms
    Ign coil 3 .36 ohms

    This seems to me like a broken pickup coil, out of spec lighting coil and can I even test the CDI with no signal from the pickup coil?

    got one stator like in new condition with the block of plate already installed . lmk . don't know if i got a cdi for it , got to look for. cdi are hard to test , you can ohm the stator and coils and compare to service manual specs .

    I took the front cover off today, I've gotten much quicker at removing the exhaust. Out of curiosity I cut the wires closer to the coils and they were both in spec. .59 ohms on the lighting coil and 540 ohms on the pickup coil. The wires were badly corroded closer to the connector. The stator coils never went bad, the wires did.

    New stator fixed the problem, CDI was good but now I have a spare GP1200R powervalves won't cycle from cranking unless they get a signal from the pickup coil. also display wouldn't read until I cranked it with pickup signal. I worded it that way so maybe in someone's future search it will show up and help them. Aand I now have a spare servomotor as well.

    Sorry to revive a very old thread, but I seem to be having very similar issues. Trying to start my ski after sitting idle for a couple years. Cranks over strong but won't fire. Display appears to be dead.

    Haven't tested for spark but assuming it's not there and I don't remember hearing the power valves cycle (will check both of these tonight). Could a bad water temp sensor cause all of these issues? Based on what I'm reading it seems like the display still works if the water temp sensor is bad

    After sitting for a couple years I would suggest a carb clean/rebuild.

    Dont assume anything.... check

    Yep, carbs were rebuilt and gas was drained prior to even trying to turn it over. Tested spark tonight and got nothing. Tested resistance on the following and everything seemed to come back within spec:

    - Water Temp Sensor: 27k ohm at 32 degrees and 1k ohm at 212 degrees
    - Lighting Coil: 45 ohm
    - Pickup Coil: 525 ohm

    Going to test voltage across rectifier and ignition coils tomorrow. Anything else I should look into?
